Because every stripper/erotic dancer has made the career choice to work in a field where their success is measured by how much money they can extract from a man's wallet by using their bodies. Seeing as they spend the majority of their time developing this skill, and it's a fairly effective skill to have when it comes to paying rent, eating, and purchasing cocaine, they end up very unskilled in virtually every other trait human beings have.
You're looking to
date a woman? This is NOT a skill you want her to have reached expert levels in, unless you've got money to burn. You're looking for a woman who is below-average in this particular skill, who's focused more on learning skills like 'being interesting'.
If you've just won the lottery and want to have a really good three months, by all means, date strippers. Alternately, if you'd like to be greeted after a long day of sitting on your ass and playing XBox by your girlfriend coming home with $2,000 she earned by rubbing her fun parts all over strangers' junk, date strippers. (Or, work your ass off all day and get outearned by your girlfriend, who spent her day rubbing her fun parts all over strangers' junk.)
This is amongst the first things fathers should tell their children. Hey, I get it, I grew up watching Married With Children. I used to think the strip club was this magical place where you could get away from the wife and talk sports with Bob Rooney. It's not. It's a horrible pit of depression where men spend exorbitant sums of money to be teased with the
idea of sex by women who have just spent the past seven hours teasing men with the idea of sex. So, no. Don't date a stripper.
Being a strippers' sidepiece follows entirely different rules which are too extensive to go into at this place in time.
